DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part thereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.

Referring to the figures generally, various embodiments disclosed herein relate to a feedback system (e.g., a haptic feedback system, an audible/visual feedback system, combinations thereof, etc.) intended to enhance the situational awareness of a user in a given situation (e.g., in an electronic game, in a real-world application, a combination of being in a physical environment while immersed in a virtual environment, etc.). When a threat or other object (e.g., an opponent, an enemy, a danger zone, etc.) is looking at (e.g., gazing, etc.), within the proximity of, and/or obstructing movement of a user (or virtual character) of the feedback system, feedback (e.g., haptic feedback, audible feedback, visual feedback, etc.) may be provided to the user to make him/her aware of objects not in his/her field of view, other people or virtual characters gazing in his/her direction, and/or to identify an object in the user's proximity as a threat or hazard. Ideally, the feedback becomes second nature to the user of the feedback system such that he/she develops an intuitive sense of the surroundings and/or a virtual environment. The feedback may be haptic, audible, visual, or combinations thereof, among other possibilities.

For example, electronic game players are not always aware of objects, other players, and/or threats within an electronic game, due to limitations of field of vision, distractions, skill, etc. The systems disclosed herein in accordance with various embodiments provide players with feedback regarding a primary object (e.g., a character used by the electronic game player, a vehicle driven by the electronic game player, etc.) and a secondary object (e.g., other virtual characters, vehicles, dangers, remote from the primary object, a distal object, etc.). The feedback may be generated based on various data regarding the primary object, secondary objects, a surrounding virtual environment, etc., and may be provided so as to provide an indication of a directness of a gaze, a virtual distance, a virtual direction, an affiliation, a threat level (or nature or type of the secondary object), a relative velocity, an absolute velocity, a relative acceleration, an absolute acceleration, and the like between the primary object and the secondary object. The feedback may also provide a user of the virtual character with an indication of a condition (e.g., health, armor level, etc.) of the virtual character and/or the user themselves (e.g., heart rate, breathing patterns, etc.). The feedback system may also be configured to provide a user immersed within a virtual environment an indication of a physical environment surrounding the user that is at least partially obstructed by a display device (e.g., virtual reality glasses, etc.) of the feedback system.

Similarly, users may likewise use the systems disclosed herein for real-world applications such as driving, treatment for sight or hearing-impaired persons, aviation, sports, combat, construction, etc. For example, a paintball player may not always recognize/see other players of an opposing team or may have an opposing player sneak up from a side or rearward position. The systems disclosed herein in accordance with various embodiments are configured to provide a user of the feedback system with feedback (e.g., haptic feedback, audible feedback, visual feedback, etc.), thereby increasing the user's awareness of potential threats or other information that may be conveyed through audible, tactile, and/or visual stimulation. In another example, a construction worker may be working in a potentially hazardous area (e.g., on a construction site with a ledge, etc.) or a factory worker may be warned about staying away from dangers within a factory (e.g., near rotating/moving equipment or hot surfaces, etc.). The feedback system may provide feedback to the user such that they have a “6th sense,” leading to an intuitive understanding of his/her surrounding to facilitate avoiding dangerous areas and/or materials.

According to an example embodiment, elements 102 may be or include a vibratory element configured to provide haptic feedback (e.g., vibrations, mechanical stimulations, etc.) to a user regarding a secondary object (e.g., a gaze, a proximity, a threat level, etc. of another virtual character, etc.), an event within the electronic game, a physical object near the user of feedback device 100, and/or a condition of the user's virtual character and/or the user. For example, element 102 in some embodiments is or includes a vibration device or similar component configured to provide tactile feedback (e.g., haptic feedback, vibrations, etc.) to a user regarding a secondary object, an event within the electronic game, a physical object near the user of feedback device 100, and/or a condition of the user's virtual character and/or the user. The frequency, amplitude, waveform, and/or other characteristics of vibrations of elements 102 may be varied to provide indications of direction, relative position, relative velocity, absolute velocity, relative acceleration, absolute acceleration, affiliation, threat level, nature, a condition change, an event, an object warning, and the like to the user.

In some embodiments, feedback device 100 includes an audible element such as a speaker (e.g., external speaker, head phones, ear buds, etc.) configured to provide audible feedback (e.g., an audible warning or notification, etc.) to a user regarding a secondary object, an event within the electronic game, a physical object near the user of feedback device 100, and/or a condition of the user's virtual character and/or the user. The speaker may be implemented in any suitable location, and any suitable number of speakers may be utilized. In some embodiments, multiple speakers may be utilized. The speakers may be worn on or within one or both ears of a user, or externally located from the user or feedback device 100 (e.g., television speakers, stereo system speakers, etc.). In one embodiment, the speakers are stereophonic such that a stereophonic warning is provided to users by way of feedback device 100. While in some embodiments the speakers are worn by a user (e.g., on an ear, etc.), in other embodiments, the speakers are carried by another piece of equipment, such as headgear 104, a vehicle, portable device 76, television 72, etc. The pitch, volume, tone, frequency, and/or other characteristics of an audible warning/notification may be varied to provide indications of direction, relative position, relative velocity, absolute velocity, relative acceleration, absolute acceleration, affiliation, threat level, nature, a condition change, an event, an object warning, and the like to the user.

In some embodiments, feedback device 100 includes visual elements such as one or more lights or displays configured to provide visual warnings or notifications to a user regarding a secondary object (e.g., a gaze, a proximity, a threat level, etc. of another virtual character, etc.), an event within the electronic game, a physical object near the user of feedback device 100, and/or a condition of the user's virtual character and/or the user For example, one or more lights (e.g., LEDs, etc.) may be provided within headgear 104 (e.g., to the peripheral side of each eye, etc.). A brightness, a color, a blinking frequency, or other characteristic of the light may be varied to provide indications of direction, relative position, relative velocity, absolute velocity, relative acceleration, absolute acceleration, affiliation, threat level, nature, a condition change, an event, an object warning, and the like to the user. In some embodiments, feedback device 100 includes a combination of feedback elements, including one or more of haptic, audible, visual, and the like.

Feedback device 100 may provide a user of feedback system 10 with enhanced awareness of his/her virtual surroundings such that he/she may provide an input to input device 80 that corresponds with the feedback. For example, the user may provide a touch input and/or motion input to controller 82 to move a virtual character a certain direction, perform a specific task, or the like based on the feedback received. By way of another example, the user may provide a voice command to headset 84 to control the actions of the primary object, provide team members with information regarding enemies (e.g., players on another team, etc.) based on the feedback, and the like based on the received feedback from feedback device 100. By way of yet another example, the user may provide touch sensitive inputs to touch sensitive device 86. The relative locations of touch sensitive device 86 may substantially correspond to the feedback provided by feedback device 100. For example, the user may feel a vibratory sensation on the back of his/her head from headgear 104. The user may associate the location of the haptic feedback on their head to the near side (i.e., the side closest to the user, etc.) of touch sensitive device 86. By touching the corresponding location on touch sensitive device 86, the virtual character may move accordingly. For example, the virtual character may turn towards the inputted direction, begin moving in the inputted direction, or start shooting in the inputted direction, among other alternatives. By way of still another example, feedback device 100 may provide a user of feedback system 10 with enhanced awareness of his/her physical surroundings such that he/she may avoid walking into objects in the physical environment (e.g., when using VR glasses 74, etc.).

In some embodiments, feedback device 100, sensor system 90, input device 80, and/or display device 70 are provided by a single device such that the single device provides both input to processing circuit 30 (e.g., to control the virtual character, etc.) and output/feedback to the user (e.g., to provide enhanced situational awareness, etc.). For example, touch sensitive device 86 may be integrated into headgear 104 such that a user may provide a touch input directly in the location the feedback is experienced. By way of example, if haptic feedback is provided to the temple of the user (e.g., indicating an enemy to their side, etc.), the user may touch the temple location on their head, and touch sensitive device 86 may take appropriate action (e.g., turn in the direction of the touch input, etc.). In some embodiments, feedback devices 100 such as headgear 104, band(s) 106, and/or article(s) of clothing 108 are configured to provide input to feedback system 10 through motion/movement of the user. By way of example, feedback device 100 may include motion sensors that track the movement of a portion of the user (e.g., an arm, a leg, etc.). For example, a user may turn his/her head and headgear 104 may track the motion and provide input such that the virtual character turns or looks accordingly. By way of another example, the user may be wearing bands 106 on his/her wrists such that bands 106 provide input regarding the location of the virtual characters hands/arms based on the movement of the users hands/arms (e.g., such as the motion of the user's arm when throwing a punch in a fighting game, etc.). In some embodiments, sensor system 90 (e.g., via a camera system, etc.), display device 70 (e.g., portable device 76, VR glasses 74, etc.), and/or feedback device 100 (e.g., headgear 104, bands 106, clothing 108, etc.) track the movement of the user. Feedback system 10 may then compare the motion data gathered by sensor system 90, display device 70, and/or feedback device 100 to provide a more accurate input to control movements and actions of the primary object.

Feedback Regarding a Virtual Character

Referring now to FIG. 5, in some embodiments, elements 102 are configured to be selectively and dynamically activated and deactivated based on an orientation of the head of the primary object (e.g., P₁, etc.) relative to the secondary object(s) (e.g., O₁, O₂, etc.). As shown in FIG. 5, secondary objects O₁ and O₂ are in close proximity (e.g., pose a possible threat, etc.) to primary object P₁ within virtual environment 110, while secondary object O₃ is not within close proximity (e.g., does not pose a threat, substantially far from primary object P₁, etc.). In one embodiment, feedback device 100 provides the user with feedback such that the user has a heightened awareness of the secondary objects and/or threats outside of his/her field of view. For example, as shown in FIG. 5, secondary object O₂ is not within the field of view of primary object P₁ such that user is not able to see secondary object O₂ on display device 70. In other embodiments, feedback device 100 further provides the user with feedback for secondary objects within the user's field of view to reinforce the intuitive understanding of what each vibration (or other feedback signal such as audible or visual) represents as described more fully herein. For example, as shown in FIG. 5, secondary object O₁ is within the field of view of primary object P₁ such that user is able to see secondary object O₁ on display device 70. In one embodiment, feedback device 100 provides the user with feedback when the primary object P₁ and a secondary object are not in contact. In some embodiments, feedback device 100 also provides the user with feedback when the primary object P₁ and a secondary object are in contact (e.g., a punch or kick hitting the primary object, etc.).

Referring again to FIG. 5, in some embodiments, elements 102 are configured to be selectively and/or dynamically activated and deactivated by control system 20 based on gaze data of a secondary object (e.g., O₁, O₂, O₃, etc.) of an electronic game. The gaze data may include an indication of a gaze direction of a second virtual character relative to a primary object (e.g., P₁, etc.). The gaze data may provide an indication to the position and view angle of the secondary objects. The position of a virtual character may be defined by a global coordinate system such as a Cartesian coordinate system (e.g., X position, Y position, Z position, etc.) within virtual environment 110. The view angle of a virtual character may be defined based on the pitch, yaw, and roll of the line of sight of the virtual character, i.e., the deviation of the virtual character's line of sight from “zero” (i.e., straight ahead). Thus, based on the position of the primary object P₁ (e.g., X, Y, Z coordinates, etc.), and the position and view angle of the secondary object(s) (e.g., O₁, O₂, O₃, etc.), control system 20 may determine whether the primary Object P₁ is in or substantially near being within the line of sight of one or more secondary objects.

In one embodiment, feedback device 100 provides the user with feedback such that the user has a heightened awareness of the secondary objects and/or threats that are looking at and/or within a certain distance of the primary object. For example, as shown in FIG. 5, secondary objects O₁ and O₂ are in close proximity (e.g., pose a possible threat, etc.) to primary object P₁ within virtual environment 110, while secondary object O₃ is not within close proximity (e.g., does not pose a threat, substantially far from primary object P₁, etc.). Further, as shown in FIG. 5, secondary objects O₁, O₂, and O₃ are looking in the direction of primary object P₁. In some embodiments, feedback is provided to a user of the primary object in response to a gaze of a secondary object coming within an angle threshold of the primary object. In some embodiments, the feedback regarding the gaze of a secondary object may provide information such as a distance between the primary object and the secondary object, a directness of the gaze or level of attention (e.g., incidental looking, tracking and following, locked and loaded targeting, etc.), type of secondary object looking (e.g., high threat character, low threat character, etc.), and/or the like. In one embodiment, feedback device 100 provides feedback for any secondary object looking in the direction of the primary object P₁. In some embodiments, feedback device 100 does not provide feedback to the user regarding a secondary object within the line of sight of the primary object P₁ (e.g., secondary object O₁, etc.). In other embodiments, feedback device 100 provides the user with feedback for secondary objects within the user's field of view to reinforce the intuitive understanding of what each vibration (or other feedback signal such as audible or visual) means. In some embodiments, feedback device 100 does not provide feedback to the user regarding a secondary object substantially far from the primary object P₁ (e.g., secondary object O₃, etc.).

The feedback may be binary (e.g., on or off, etc.). The feedback may be scaled based on the angle between the primary object and the line of sight of the secondary object. Thus, the feedback may indicate more urgency as the line of sight of the secondary object approaches the primary object. The feedback may also be scaled based on a distance between the primary object and the secondary object such that secondary objects closer to the primary object cause increased feedback as compared to secondary objects further from the primary object. The feedback may also vary based on the type of secondary object and/or threat level of the secondary object. The feedback may provide an indication to range and/or bearing to the secondary object through different classes of sensations, different intensities, different frequencies, and/or different pulse patterns. The feedback may also indicate the number of secondary objects looking at the primary object or a certain point or destination.

According to one embodiment, feedback device 100 provides two dimensional information (e.g., left, right, front, back, etc.) to a user regarding the position of the secondary object in relation to the primary object. For example, if the secondary object is behind the primary object (e.g., while looking at the primary object, etc.), feedback device 100 may provide haptic feedback (or another type of feedback) via elements 102 to a rear portion of the user (e.g., back, rear of head, rear of neck, etc.) to make the user aware of the unseen secondary object behind the primary object. In other embodiments, feedback device 100 provides three dimensional information (e.g., up, down, up at an angle, etc.) to the user regarding the position of the secondary object (e.g., looking at the primary object, etc.) in relation to the primary object. For example, if the secondary object is to the side and above the primary object, feedback device 100 may provide haptic feedback via elements 102 to a side portion of the user (e.g., between the top and side of the user's head, etc.). In another example, the feedback system 10 may provide visual feedback via elements 102 by flashing a light in the users peripheral vision (e.g., on the side the secondary object is located, etc.) or emitting an audible tone in an ear corresponding to a location of the secondary object with respect to the users view of the virtual environment (e.g., emitting an audible tone in the right ear of a user when a secondary object is located somewhere on the right side of the users view of the virtual environment, etc.).

According to an example embodiment, elements 102 of feedback device 100 provide metadata denoting situations within the electronic game (e.g., not only directional information based on position and/or gaze direction, etc.). By way of example, feedback module 60 may be configured to vary the frequency, amplitude, waveform, etc. of an output (e.g., vibrations, sounds, lights, etc.) of elements 102 to provide indications of different types of information to the user regarding the primary object and/or the secondary object based on the first data, the second data, the condition data, the display data, the object data, and/or the event data. In one embodiment, elements 102 denote a change in relative position between the primary object and the secondary object. In further embodiments, the feedback is configured to provide an indication of a relative distance, a relative velocity, an absolute velocity, a relative acceleration, and/or an absolute acceleration between the primary object and the secondary object. For example, the frequency of vibratory feedback may be increased or decreased with the relative velocity of the secondary object (e.g., another user controlled character, computer controller character or object, etc.), and the amplitude of the vibratory feedback may be increased or decreased with the relative distance between or proximity of potentially threatening objects. As such, in one embodiment, as the relative velocity between the primary object and the secondary object increases and/or the distance decreases, the vibratory feedback may increase in frequency and amplitude. Conversely, should the user take action to avoid the secondary object (e.g., by slowing down, changing direction, etc.) to decrease the relative velocity between users and/or increase the distance, the vibratory warning may decrease in frequency and amplitude. The same may be true for audible and/or visual feedback.

In yet further embodiments, the feedback is configured to provide an indication of an affiliation and/or a threat level/nature of the secondary object. For example, non-threatening objects (e.g., allies, teammates, etc.) may be ignored (e.g., no feedback is provided, etc.). On the other hand, threatening objects (e.g., enemies, players on other team, opponents, etc.) may cause control system 20 to provide feedback to the user via feedback device 100. Likewise, the feedback may vary in amplitude, frequency, waveform, etc. based on a threat intensity. For example, a high threat object (e.g., a boss character, a high skilled player, etc.) may cause a more frequent and higher amplitude vibratory, audible, and/or visual response from elements 102. Conversely, a low threat object (e.g., low skilled player, minion, etc.) may cause a less frequent and lower amplitude vibratory, audible, and/or visual response. In some embodiments, feedback device 100 further provides the user with various intensities of feedback based on the direction between the primary object and the secondary object relative to an orientation of the primary object and/or an orientation of the secondary object. For example, a secondary object may be classified as a high threat object if the secondary object is looking at the primary object or a low threat object if the secondary object is looking away from the primary object. As another example, a secondary object may be classified as a high threat object if the primary object is not looking at the secondary object or a low threat object if the primary object is looking at the secondary object.

In some embodiments, feedback device 100 is configured to provide directional information to the user. In one embodiment, the directional information indicates a proposed direction of movement of the primary object. By way of example, in a racing game, feedback device 100 may provide directional cues to notify the user of an upcoming turn in a race track. By way of another example, feedback device 100 may provide the user with feedback to propose a direction of travel such that the user leads a virtual character along a certain path, towards a secondary object, and/or away from a threat, among other possibilities. In other embodiments, the directional information indicates a direction of virtual gravity. For example, in some games, a virtual character may become disoriented (e.g., from an explosion, etc.) and not be able to gain bearing for a certain amount of time. In this instance, feedback device 100 may provide directional cues to reorient the user of the virtual character with virtual environment 110 (e.g., such as the direction of virtual gravity, etc.). In an additional embodiment, the directional information provides an indication of a specific point or locations of interest. For example, the points may be static points such as a home base or planet, or the points may be moving such as targets (e.g., enemies, etc.) that the user may be tracking or being tracked by. The static points may be valuable during combat or other types of play to orient the user with where the user is headed or with what the user is guarding during moments of disorientation.

In some embodiments, feedback system 10 is configured to recognize boundaries within virtual environment 110 and provide feedback through feedback device 100 based on the respective boundary. For example, feedback device 100 may warn a user of an upcoming cliff or obstacle within virtual environment 110. By way of another example, feedback device 100 may lead a user to a doorway or passage within the virtual environment. By way of yet another example, feedback device 100 may recognize and notify a user of walls or virtual boundaries (e.g., such as in dark caves, holorooms, etc.) that the user may or may not be able to see.

According to an example embodiment, elements 102 are configured to be selectively and/or dynamically activated and deactivated by control system 20 based on condition data. The condition data may provide an indication of a condition (e.g., health, power, shield, etc.) of the virtual character of a user within an electronic game. Feedback system 10 may be configured to provide an indication to the user that the health, armor, or other condition of the virtual character is declining below a threshold value while in the virtual environment (e.g., critical health, percentage of health lost, etc.). This may substantially eliminate the need for the user to look at visual indications of these conditions on a user interface (e.g., monitor, television, etc.), which facilitates quicker and appropriate reactions. The feedback regarding the condition of the virtual character may be any of a tactile notification, a visual notification, and/or an audible notification. The tactile notification may be a throb, a buzz, a tap, and/or a pulse. The feedback may encode information about which condition of the virtual character is declining, what the current level of the condition is (e.g., critical health, etc.), and/or how much time or damage that can be inflicted before a condition reaches a critical level.

In some embodiments, feedback system 10 monitors the status of a user's team or enemy team and relays information regarding the status to each user. For example, feedback system 10 may provide feedback to a user when a player is killed via feedback device 100. In one embodiment, feedback device 100 provides haptic feedback to inform the players of how many players are alive or dead via a number of vibrations. In other embodiments, the feedback may be an auditory message (e.g., such as “player X has been killed”, “five players remain”, etc.).

Parameters in which the feedback is provided to a user may be modified by at least one of the user based on preference and control system 20 based on a chosen difficulty setting (e.g., easy, medium, hard, etc.), according to an example embodiment. For example, a range (e.g., distance, etc.) in which the user is first alerted of a secondary object may be altered via a user chosen setting or predefined by the game difficulty selected by the user. Similarly, the user may choose the type of objects for which to be alerted about (e.g., enemies, friendlies, based on threat level, nature, etc.). In one embodiment, a squelch function is used to tune out (e.g., suppress, etc.) excess noise (e.g., non-threatening objects, etc.).

According to an example embodiment, elements 102 of feedback device 100 (e.g., haptic elements, visual elements, audible elements, etc.) are selectively and/or dynamically activated and deactivated by control system 20 based on conditions or settings within the game corresponding with the event data and/or actions taken by the primary and secondary object (e.g., indicated by the first data and the second data, etc.). The use and/or availability of feedback with a game may be controlled by control system 20 responsive to the event data, the first data, and/or the second data.

In some embodiments, the availability of feedback is based on the game level/situation or a change thereof. By way of example, feedback may be disabled or scrambled (e.g., false feedback provided, miscalibrated, etc.) by control system 20 during a portion of a game to increase the difficulty. By way of another example, feedback may be disabled during a situation where the primary object (e.g., virtual character) becomes disoriented (e.g., from a flash bang grenade in a war game, etc.). By way of yet another example, as the user progresses through the game and reaches new checkpoints, milestones, and/or levels, the availability of the feedback may change (e.g., decrease, increase, etc.). For example, feedback may be disabled or hindered during a portion of the game when the primary object controlled by the user is facing a boss character or a character with a feature/ability/perk to disable/hinder feedback abilities.

In some embodiments, the availability of feedback is based on a primary object's or a user's experience, performance, and/or skills. For example, a virtual character with better attributes (e.g., strength, speed, aim, etc.), perks (e.g., special weapons, powers, etc.), and/or skills than other virtual characters may not be compatible with a feedback feature. In another example, a user may be rewarded the ability to activate feedback based on a level of skill (e.g., reaching a certain rank, level, prestige, etc.). In other embodiments, the availability of feedback is based on the performance of other users or secondary objects within the game. For example, if a secondary object is outperforming the primary object, the user of the primary object may be allowed to implement feedback capabilities, while the user of the secondary object may have feedback capabilities reduced or disabled.

In some embodiments, the availability of feedback is based on a current virtual environment. By way of example, feedback may be disabled in a harsh environment of the electronic game (e.g., during a storm, in a dark cave, etc.). In additional embodiments, the availability of feedback is based on a difficulty setting of the game. By way of example, a user playing a game on a relatively easy setting may be provided substantial amounts of feedback to enhance their awareness within the game and aid in the reduction of the difficulty. While a user playing a game on a relatively difficult setting may be provided with minimal amounts of feedback or none at all to increase the difficulty.

In some embodiments, the availability of feedback is based on the purchase or acquisition of feedback within the game or from a game marketplace (e.g., an app store, etc.). For example, feedback may be treated like a special item or skill that is purchasable (e.g., via points or virtual money earned during game play, etc.) within the game to increase the awareness of the virtual character (i.e., the user of the virtual character) regarding the surrounding virtual environment and secondary objects. In another example, feedback may require an additional purchase not included with the game from a store (e.g., an electronics retail store, etc.) or online game marketplace.

In some embodiments, the availability of feedback is based on an operational mode of feedback device 100 (e.g., on, off, an active state, an inactive state, etc.). According to an example embodiment, feedback device 100 is operable in a first mode of operation (e.g., an active state, an on state, etc.) and a second mode of operation (e.g., an inactive state, a standby state, an off state, etc.). In one embodiment, the first operational mode and/or the second operational mode indicate a specified sensitivity setting for feedback device 100. The specified sensitivity setting may be user defined or processor controlled. The specified sensitivity setting may indicate an amount of feedback output for a given input (e.g., distance based, threat based, etc.). In another embodiment, the first operational mode and/or the second operational mode indicate a specified event responsiveness for feedback device 100 (e.g., an amount of feedback for certain events or situations, etc.). In other embodiments, the first operational mode and/or the second operational mode indicate a specified feedback presentation for feedback device 100 to provide to a user (e.g., visual, audible, or tactile feedback; a frequency, amplitude, etc.). In some embodiments, the first operational mode and/or the second operational mode indicate a specified availability for feedback device 100 to provide feedback to a user.

In one embodiment, the operational mode of feedback device 100 is controlled by a user (e.g., by pressing an on/off button, etc.). In another embodiment, the operational mode of feedback device 100 is controlled by control system 20. Control system 20 may be configured to reconfigure feedback device 100 between the active state and the inactive state based on at least one of the event data, the first data, user data, and the second data (as described above with regards to the availability of the feedback). In one embodiment, the possession, settings, or operational mode of feedback device 100 is represented within an electronic game by a tertiary object (e.g., an item the user may pick up or obtain with the primary object, etc.). For example, control system 20 may activate feedback capabilities in response to a user obtaining a certain item (representing the activation of feedback device 100) within a game.

In some embodiments, feedback device 100 is controlled by control system 20 to operate better (e.g., be more sensitive to surroundings, etc.) for some primary or secondary objects than others. For example, some enemies (e.g., other players, virtual characters, etc.) may not be detected as well as others, such as ninjas or leopards. In one embodiment, a user is able to purchase or acquire an invisibility/sneakiness skill or ability for a primary object such that an opponent's feedback device 100 does not notify the opponent of the user's primary object. In another embodiment, a user is able to purchase or acquire a disruption skill for a primary object such that an opponent's feedback device 100 provides false feedback (e.g., provides corrupt directional feedback, introduces fake objects, etc.) to the opponent. In still another embodiment, a user may choose to use another character's perspective (e.g., of a teammate or opponent with or without permission, etc.). For example, a user may use a teammate's virtual character's perspective to gain a greater awareness of threats ahead or in another location of the virtual environment. In some embodiments, the availability of feedback is based on any combination of the aforementioned event data and/or characteristics (e.g., a level, a situation, a difficulty setting, a current virtual environment, a performance level or characteristic of the user, a performance level or characteristic of other users, an operational mode of feedback device 100, etc.).

According to yet another example embodiment, processing circuit 30 is configured to control the operation of elements 102 to provide a sense of at least one of a presence, a distance, and a direction of an object relative to the user of feedback device 100. The feedback may be based on at least one of a distance of an object (e.g., secondary object, another person, etc.) relative to the user (or primary object), a direction of the object relative to the user, a nature/threat level of the object, and a user response to previously-provided feedback. The feedback provided by elements 102 may include, but are not limited to, a vibration, a stroke or swipe, an acoustic stimulation, a visual stimulation, a temperature change, a moisture change, a lubrication, and/or an electrical stimulation. The vibration may be provided by a vibratory element. The stroke or swipe may be provided by a plurality of vibratory elements actuated in succession, simultaneously, and/or in a specific pattern (e.g., the vibratory elements are arranged in a linear pattern such that each may provide vibratory feedback to a user along the pattern, etc.). The temperature change may be provided by a heating/cooling element (e.g., a resistive heating element, a heating element that utilizes a chemical reaction, a fan, etc.). The moisture or lubrication may be provided by a nozzle attached to a fluid reservoir (e.g., a water tank, etc.) or a humidifying material or device. The electrical stimulation may be provided by a device configured to provide electrical impulses (e.g., electrical muscle stimulation, etc.).

In one embodiment, the feedback is derived from, modulated by, and/or accompanied by audio information. By way of example, using audio information, feedback device 100 may provide a user with feedback derived from the audio information indicating where a sound is coming from. By way of another example, in a situation where music within an electronic game changes, processing circuit 30 may modulate the feedback based on the music. For example, a change in the background music may indicate an intense or more difficult portion of the electronic game is occurring, where processing circuit 30 may adjust the feedback based on the situation. By way of yet another example, the feedback may be provided in the form of or accompanied by an audio output (e.g., audible feedback, from a speaker, etc.), as described above. The audio information may include a musical score, a tone, a notification, etc. In another embodiment, the feedback is accompanied by visual information supplied to the user of feedback system 10 or visual information is withdrawn from the user. By way of example, feedback device 100 may include a visual element, such as an LED light, configured to provide visual feedback. By way of another example, processing circuit 30 may provide a visual indication on display device 70 or remove the visual indication from display device 70. For example, processing circuit 30 may provide visual feedback in the form of a message (e.g., a warning, an update, etc.) or direction arrow (e.g., indicating a direction of an object, etc.) on display device 70.

Feedback Derived from Outputs of an Electronic Game

In some embodiments, feedback system 10 uses multi-channel audio data or information to localize the origin of sounds in a game and converts the sound information to feedback (e.g., haptic feedback, etc.) that indicates the virtual spatial location of the audio to the user. Feedback device 100 may connect (via any suitable wireless or wired protocol) to an audio output of feedback system 10 (e.g., a game console, a computer, a smart phone, a tablet, an audio receiver, etc.) and obtain three-dimensional audio information. Multi-channel audio operates by varying the intensity and timing of sounds to create the illusion that the sounds are being generated from a specific spatial location relative to the hearer. Feedback system 10, via processing circuit 30, may interpret raw multi-channel audio data and determine where sounds are arising from relative to the user. Processing circuit 30 may then convert the audio data into feedback to help the user better identify where the sounds are coming from. In turn, processing circuit 30 is configured to provide, for example, haptic feedback to a user via feedback device 100 to indicate specific range, elevation, and/or bearing information that may be substantially easier to interpret than audio coming from headphones or a surround sound system. This may be particularly useful in an electronic game that outputs multi-channel (e.g., 5-channel, 7-channel, etc.) audio where the user is using stereo headphones. Converting the multi-channel audio information into haptic feedback may increase a user's competitive advantage in the electronic game. The user may be able to more quickly identify, for example in a first-person shooter game, where shots are coming from than if the user were solely using the stereo headphones. For example, if a virtual character is being shot at in a first-person shooter game, and the user cannot locate where it is coming from, feedback device 100 may provide the user with haptic feedback to allow the user to identify the origin (e.g., the location relative to the virtual character, etc.) of the sound (e.g., a gunshot, etc.). This also facilitates the integration of feedback system 10 with an electronic game without the source code of the electronic game supporting feedback system 10.

In some embodiments, a similar concept may be generalized to convert many different types of in-game information into feedback. For example, many electronic games display a “bird's eye view” map, showing the location and/or orientation of the primary object, team members of the user of the primary object, and/or secondary objects (e.g., opponents, enemies, etc.) within a virtual environment. Processing circuit 30 may interpret this visual information and convert it to feedback, thereby not requiring the user to actually look at the in-game map. There are numerous other features expressed visually within an electronic game that may also be converted to feedback to be provided to a user of feedback system 10.

In one embodiment, a portable device (e.g., a mobile phone, smartphone, tablet, a laptop, a camera enabled device, portable device 76, etc.) includes and/or operates a computer vision or machine vision application (e.g., stored in memory of the portable device and controlled by a processing circuit of the portable device, etc.) that uses a sensor (e.g., a camera or other sensor, portable device sensor 96, etc.) of the portable device. The machine vision application is communicably and operatively coupled to the sensor to monitor and/or observe particular user interface (UI) features of the electronic game displayed on display device 70. The UI features may include features such as a virtual environment, a radar, a map, a primary object, a secondary object, and/or other display features or symbols that symbolically provide representations of information (e.g., location, movement, affiliation, display data, etc.) regarding secondary objects (e.g., other players, teammates, enemies, obstacles, etc.). The machine vision application may be configured to interpret the UI features and/or symbols and selectively communicate the information from the UI features to feedback device 100. Feedback device 100 may then provide the information to the user through haptic, visual, and/or audible feedback.

The information from the UI features may be provided to a wearer of feedback device 100 through a tactile output, a visual output, an audio output, or a combination thereof. For example, the sensor of the portable device and the machine vision application may determine that a secondary object (e.g., a virtual enemy, etc.) is coining up behind the primary character of the user in a virtual environment. In this case, the output may be an audio indication such as, but not limited to, an audible output providing the phrase “Behind you!”, “At your six,” or the like. Alternatively, the audible output may be used in conjunction with a tactile output which may more accurately indicate where the secondary object is (e.g., relative to the primary object or character, etc.) or may indicate some other characteristic about the secondary object (e.g., speed, type, threat level, affiliation, distance, etc.).

In some embodiments, the machine vision application may be configured (e.g., programmed and/or tuned, etc.) for specific electronic game titles, electronic game types (e.g., first person shooters, third-person shooters, racing, turn-based, sports, etc.), game consoles (e.g., PC, Xbox® PlayStation®, Nintendo®, etc.), and/or styles of different electronic game developers. In some embodiments, the machine vision application is configured to automatically recognize (e.g., detect, identify, etc.) the electronic game that the sensor is monitoring (e.g., trying to interpret, etc.) based on the UI features on the display of display device 70. The machine vision application may be further configured to implement feedback settings and/or parameters specifically designed for the particular electronic game detected (e.g., user defined according to preference and/or difficulty, predefined within the machine vision application, etc.). In other embodiments, the machine vision application is configured to prompt a user to input an identifier (e.g., title, etc.) indicative of the electronic game he or she desires to use the machine vision application with (e.g., via a drop down menu and/or fill in box provided by a graphical user interface of the machine vision application of portable device 76, etc.). In some embodiments, the machine vision system may use a generalized setting when the machine vision application is presented UI features (e.g., which are presented on the display to the sensor of the portable device, etc.) that the machine vision application may not necessarily be preprogrammed for or recognize. Further, in some embodiments, the machine vision application is configured to adaptively learn (e.g., through machine learning techniques, etc.) unfamiliar or unknown virtual environments that are presented before the sensor of the portable device, such that when presented with the same virtual environment on multiple occasions, the machine vision application may improve performance over time (e.g., an adaptive or continuing learning application, such that unknown virtual environments become known and stored in memory for subsequent use, etc.).

Referring now to FIG. 6, portable device 76 may be used to facilitate the integration of feedback system 10 with an electronic game without the source code of the electronic game supporting feedback system 10. For example, feedback may be provided to a user of an electronic game via the feedback system 10 without the feedback system 10 having to be directly connected to the electronic game, without the software of the electronic game having to be altered to support the feedback system 10, and/or via a user's personal portable device(s) 76 (e.g., smartphone, tablet, laptop, webcam, other camera enabled device, etc.). Therefore, feedback may be provided from a feedback system 10 that is completely external from (e.g., not connected to, may or may not be supported by, not in communication with, etc.) the electronic game and display device 70.

As shown in FIG. 6, portable device 76 may be positioned such that portable device sensors 96 (e.g., a camera device, etc.) is able to acquire information and/or display data from virtual environment 110 currently being displayed by display device 70, such as television 72 or other display devices (e.g., a monitor, a projection screen, etc.). According to one embodiment, portable device sensors 96 of portable device 76 are insensitive to the precise orientation of portable device 76. Portable device 76 may thereby acquire the display data from virtual environment 110 irrespective of the orientation (e.g., tilt angle, view angle, etc.) of portable device 76 relative to display device 70 (e.g., as long as portable device sensor(s) 96 have some line of sight of virtual environment 110, etc.).

Virtual environment 110 may include various display data that provide indications regarding the current location of the primary object P₁ (e.g., within a map, virtual world, etc.), surrounding virtual objects (e.g., secondary objects, houses, buildings, vehicles, geographical landscapes, etc.), a direction of travel (e.g., of the primary object, of one or more secondary objects, etc.), a rate of travel (e.g., velocity, acceleration, of the primary object, of one or more secondary objects, etc.), range information (e.g., between the primary object and one or more secondary objects, etc.), bearing information (e.g., between the primary object and one or more secondary objects, etc.), affiliation information (e.g., of one or more secondary object, etc.), threat level information (e.g., of one or more secondary objects, etc.), attribute information (e.g., of one or more secondary objects, etc.), a gaze direction (e.g., of the primary object, of one or more secondary objects, etc.), etc.

As shown in FIG. 6, virtual environment 110 may also include a bird's eye view map, shown as radar map 112 (e.g., located in a corner of the display, etc.). Radar map 112 may display the location and/or orientation of the primary object P₁, team members of the user of the primary object P₁, and/or secondary objects (e.g., opponents, enemies, O₁, O₂, O₃, etc.) relative to each other within virtual environment 110. Radar map 112 may provide display data including relative positions (e.g., of primary object P₁ to secondary objects O₁, O₂, etc.), range and/or distance (e.g., between primary object P₁ to secondary objects O₁, O₂, etc.), and/or bearing (e.g., between primary object P₁ to secondary objects O₁, O₂, etc.), among other possibilities.

According to one embodiment, portable device 76 is configured to acquire the display data from the display of virtual environment 110 and/or radar map 112 with portable device sensors 96. According to an example embodiment, portable device 76 enables a user of an electronic game to acquire the display data for feedback purposes (e.g., haptic, audible, visual, etc.) without requiring the purchase of additional hardware components (e.g., the user may utilize commonly owned camera enabled portable electronic devices, etc.). In one embodiment, portable device 76 includes processing circuitry (e.g., such as processing circuit 30, an application stored within the memory of portable device 76, etc.) configured to analyze the display data. Therefore, portable device 76 may include at least a portion of sensor system 90 (e.g., portable device sensors 96, etc.) and at least a portion of control system 20 such as processing circuit 30, sensor module 50, and/or feedback module 60. In other embodiments, portable device 76 is configured to provide the display data to an external control system 20 for further processing and analysis (e.g., portable device 76 acts as at least a portion of sensor system 90 only, etc.) for feedback purposes as described above.

Acquiring display data from at least one of virtual environment 110 and radar map 112 allows feedback to be provided when secondary objects may or may not be visible to the user, visible to the primary object, and/or on the screen of display device 70. For example, feedback may be provided when a secondary object is not visible within virtual environment 110 but is visible on radar map 112 (e.g., secondary objects O₂ and O₃, etc.). In another example, feedback may be provided when a secondary object is visible within virtual environment 110 to the primary object and/or the user (e.g., secondary object O₁, etc.).

According to an example embodiment, portable device 76 is configured to acquire the display data in real-time and communicate with feedback device 100 to provide feedback to the user of the electronic game. Portable device 76 may communicate with feedback device 100 using any suitable wired and/or wireless communications protocols. Portable device 76 may interpret (e.g., analyze, etc.) the display data to provide various feedback commands (e.g., haptic, visual, audio, etc. feedback) to feedback device 100 based on the display data. The feedback commands may provide indications to the user of feedback device 100 regarding position, range, bearing, velocity, among other possibilities, of secondary objects (e.g., opponents, enemies, threats, etc.) relative to the primary object P₁ controlled by the user. Thus, the user may not need to focus on the radar map 112 and/or peripheral areas of virtual environment 110, thereby increasing the user's competitive advantage in the electronic game (e.g., the user is able to focus on a more important task, on the environment ahead, etc.).

Feedback Regarding a User of a Virtual Character

Referring now to FIGS. 7A-7B, feedback system 10 may be configured to provide feedback to the user of an electronic game based on object data. The object data may provide an indication to a location, size, a proximity/distance, and/or a velocity of a physical object relative to the user and/or other characteristics of the physical object relative to the user in the physical environment. This may be particularly useful in situations where a user is playing an electronic game where he/she is physically moving (e.g., walking around, etc.) while wearing a display device, such as VR glasses 74, that at least partially obstructs the user's view of the surrounding physical environment.

As shown in FIG. 7A-7B, user P₁ is wearing VR glasses 74. In one embodiment, VR glasses 74 include portable device 76 disposed therein (e.g., within portable device retainer 78, etc.) or detachably attached thereto (e.g., an exterior wall thereof, via portable device retainer 78, etc.). In other embodiments, VR glasses 74 do not include portable device 76 or facilitate the coupling of portable device 76 thereto. In one embodiment, VR glasses 74 provide a display of virtual environment 110 that the virtual character of user P₁ is within. In other embodiments, portable device 76 provides a display of virtual environment 110 that the virtual character of user P₁ is within. As shown in FIG. 7A, VR glasses 74 and/or portable device 76 at least partially obstruct the user's view of the surrounding environment such that the user P₁ may be unaware of physical objects, such as object 120 (e.g., a wall, a stool, a piece of furniture, stairs, other hazard, other people, etc.), as he/she walks around the surrounding environment to navigate throughout virtual environment 110.

As described above, sensor system 90 is configured to acquire the object data regarding objects 120 located within the physical environment surrounding the user of feedback system 10 such that feedback device 100 may provide feedback to the user regarding objects 120 (e.g., elements 102 are selectively and/or dynamically activated and deactivated by control system 20 based on the object data, etc.). Sensor system 90 may also be configured to track movement of the user to correspond with movement and/or actions taken by the virtual character within virtual environment 110. Sensor system 90 may include an external sensor system including sensors, shown as external sensors 92, positioned throughout the physical environment, sensors position within or disposed on feedback device(s) 100 (e.g., user sensors 94, etc.) and/or display device 70 (e.g., VR glasses 74, etc.), and/or portable device sensors 96 of portable device 76. External sensors 92 may include, but are not limited to, personal security cameras, webcams, game console cameras (e.g., Kinect, etc.), computer and/or laptop cameras, and/or other sensors positioned within a user's residence or gaming area to monitor a user and/or a physical environment. The sensors of VR glasses 74 and/or portable device sensors 96 of portable device 76 may include a still camera, a video camera, a gyroscope, an accelerometer, a compass, a proximity sensor, a radar, a lidar, and/or still other sensors. Sensor system 90 may include any combination of VR glasses sensors, user sensors 94, portable device sensors 96, and external sensors 92. In some embodiments, multiple sensors create a network of sensors that are used to generate a 3D image of the user and the surroundings to increase the feedback capabilities and accuracy of the feedback system 10.

The feedback provided by feedback system 10 regarding object 120 may provide an indication that user P₁ is nearing object 120. The feedback may encode information such as a range, bearing, and/or an anticipated time until a collision (e.g., based on the relative position and velocity, etc.) between object 120 and user P₁. The feedback may provide the information through different classes of sensations (e.g., tactile, audible, visual, etc.), different intensities, different frequencies, and/or different pulse patterns. Further, feedback system 10 may provide vestibular stimulation which may cause the head of the user to bob or recoil to indicate that he/she is about to run into an object. Thus, the feedback may substantially prevent user P₁ from walking into objects 120 while walking around and immersed within virtual environment 110.

As shown in FIG. 7B, feedback system 10 may insert an associated virtual representation of object 120 into virtual environment 110, shown as virtual object 122. Virtual object 122 may be positioned within virtual environment 110 to correspond with the position of object 120 relative to user P₁ within the physical environment. Virtual object 122 may be inserted as a virtual indication to represent object 120, but the appearance of virtual object 122 may be based on the electronic game being played (e.g., the physical appearance of virtual object 122 may not resemble object 120, etc.). For example, in a war game, virtual object 122 may be a tank or other vehicle, a missile, a fence, a building wall, etc.; while in an adventure game, virtual object 122 may be a tree, a boulder, a river, etc. In other embodiments, virtual object 122 is a substantially identical virtual representation of object 120. Virtual objects 122 may be inserted into virtual environment 110 in real-time or prior to game play (e.g., using the pre-scanning method described above, etc.). Inserting virtual objects 122 into virtual environment 110 may provide a seamless gameplay experience such that the user may react to virtual objects 122 as if he/she could see objects 120 in the physical surroundings. Thus, the display of virtual objects 122 within virtual environment may substantially prevent user P₁ from walking into objects 120 within the physical environment.

Feedback system 10 may also be able to monitor the condition of the user of the virtual character (e.g., based on condition data, etc.) using various sensors positioned around the physical environment (e.g., external sensors 92, etc.) and/or embedded on/within the component of feedback system 10 (e.g., feedback device 100, display device 70, etc.). Thus, sensor system 90 may acquire condition data indicative of a condition of the user. For example, feedback system 10 may be configured to monitor conditions of the user such as heart rate, breathing patterns, temperature, sleeplessness/alertness, time of game play, SpO₂ levels, glucose levels, hydration levels, and/or other conditions that may be affected by extended or intense game play. Feedback system 10 may be configured to provide feedback to the user regarding his/her physical condition (e.g., changes thereof, condition readings exceeding or falling below a threshold value, etc.) such that the user may take appropriate action (e.g., stop playing, get some sleep, eat some food, drink some fluids, etc.).

Real-World Feedback System

According to the example embodiment shown in FIGS. 1 and 8-10C, feedback system 10 (e.g., situational awareness system, etc.) is configured to provide feedback for real-world applications. For example, feedback system 10 may be used for driving, treatment for sight or hearing-impaired persons, aviation, sports, combat, construction, etc.

Referring now to FIG. 8, area 200, usable in connection with feedback system 10, is shown according to one embodiment. As shown in FIG. 8, area 200 includes a ground surface 202 upon which a user, such as user P₁ (e.g., an athlete, a motor vehicle operator, a military personnel, construction worker, etc.), is moving. In some embodiments, user P₁ is participating in an athletic event (e.g., a paintball game, football game, an automotive race, etc.) where opponents (e.g., other users, other vehicles, etc.), such as opponents O₁, O₂, and O₃, or other obstacles (e.g., walls, posts, vehicles, etc.) are present.

In one embodiment, area 200 includes one or more external sensors 92 (e.g., remote sensors, etc.) configured to acquire external data (e.g., second data, etc.), gaze data, and/or environment data. External sensors 92 may be positioned around or within area 200, and configured to acquire various data regarding area 200, the user P₁, and/or opponents O₁, O₂, and O₃. External sensors 92 may include any suitable sensors configured to detect the position, movement (e.g., velocity, acceleration, etc.), gaze direction, identity (e.g., team affiliation, etc.), etc. of the user P₁ and/or opponents O₁, O₂, and O₃. As discussed in further detail below, additional sensors may be worn by user P₁ (e.g., as part of a head protection device, torso protection device, leg protection device, one or more head, wrist or ankle bands, as part of a team uniform, etc.) and used to acquire data regarding various users, objects, and/or a surrounding area.

Referring now to FIG. 9, user P₁ is a paintball player. In other embodiments, user P₁ may be a racecar driver, a football player, a soldier, a construction worker, a surgeon, or another person using feedback system 10. As shown in FIG. 9, user sensors 94 are configured to be worn by, carried by, or travel with a user such as user P₁. User sensors 94 may be positioned at various locations about one or more pieces of equipment or clothing worn by user P₁. In one embodiment, user sensors 94 are provided in or on headgear 104 (e.g., a helmet, a head protection device, etc.). In some embodiments, user sensors 94 are provided on one or more articles of clothing 108 or bands 106, such as a uniform, jersey, shirt, pants, belt, or a head or wrist band, etc. In some embodiments, opponents O₁, O₂, and/or O₃ wear at least one of headgear 104, bands 106, and clothing 108 including user sensor 94 and use feedback system 10.

User sensors 94 may be or include a wide variety of sensors configured to acquire various types of data regarding user P₁ (e.g., user data, first data, condition data, gaze data, etc.), area 200 (e.g., environment data, etc.), opponents O₁, O₂, and O₃ (e.g., second data, gaze data, etc.), and the like. For example, in one embodiment, user sensors 94 are configured to acquire user data regarding a user wearing user sensors 94. The user data may include a position of the user, an acceleration and/or velocity of the user, positions and/or orientations of various body parts of the user, and so on. In some embodiments, user sensors 94 are configured to acquire user data and/or gaze data regarding other users or objects (e.g., in addition to or rather than the user wearing sensors 94). The user data and/or gaze data may include a position of another user, an acceleration and/or velocity of the other user, positions and/or orientations of various body parts of the other user, an affiliation of the other user, a gaze direction of the other user, and so on. In addition, various data may be obtained in absolute terms (e.g., position, velocity, acceleration) and transformed into relative terms for two or more users (e.g., by comparing absolute values of various users, etc.).

In one embodiment, user sensors 94 are or include an inertial sensing device, such as an accelerometer, a gyroscope, and the like. In other embodiments, user sensors 94 are or include an image capture device, such as a still image and/or video camera. In further embodiments, user sensors 94 include a GPS receiver. In addition to such passive sensors, user sensors 94 may in some embodiments be or include an active sensor, such as a lidar system, radar system, sonar system (e.g., an ultrasonic sonar or sensing system), etc.

In other embodiments, user sensors 94 are configured to provide data regarding team affiliations of various users. For example, user sensors 94 in some embodiments are or include a beacon, such as an RFID tag, that may be carried by each user. The RFID tags may provide team affiliation data, and may provide user-specific data, such as a user height, weight, etc. (e.g., through near field communication, etc.). In one embodiment, the beacons communicate with one another. In other embodiments, signals from the beacons are received by external sensors 92 to be provided to control system 20.

In one embodiment, user sensors 94 are configured to acquire gaze data indicative of an orientation of a user's head (e.g., a direction in which the user is facing, a tilt of the head relative to the horizon, etc.). As such, user sensors 94 may be spaced about the user's head to form a sensor array configured to acquire positional data regarding the orientation of the user's head. In some embodiments, user sensors 94 are configured to scan an environment to acquire environment data regarding potential hazards or dangers near the user. In some embodiments, user sensors 94 are configured to acquire condition data regarding a condition of the user.

In some embodiments, feedback system 10 is implemented as part of a vehicle operator system, such that one or more user sensors 94 are provided as part of a vehicle. For example, a vehicle may include one or more user sensors 94 configured to provide sensor data to control system 20 regarding other vehicles or objects. Furthermore, the vehicle (e.g., a vehicle computer or control system, etc.) may be configured to provide additional data regarding operation of the vehicle, such as information regarding velocity, acceleration, braking conditions, and the like. A user (e.g., a motorcycle operator, a racecar driver, a bicycle rider, etc.) may wear a head protection device such as headgear 104 (e.g., helmet such as a football, baseball, or hockey helmet, a motorcycle or bicycle helmet, a soldier helmet, a ski helmet, etc.) configured to house additional user sensors 94 and/or portions of control system 20 and provide feedback. For example, feedback may be provided to a driver of a first vehicle to indicate that a driver of a second vehicle is in the blind spot of the driver of the first vehicle. As a result, the feedback may substantially reduce the likelihood of a collision between the two vehicles.

Referring back to FIGS. 8-9, the various sensors (e.g., external sensors 92, user sensors 94, etc.) acquire data regarding user P₁, opponents O₁, O₂, O₃, and/or area 200 and provide the data to control system 20. Control system 20 is configured to control operation of feedback device 100 to provide feedback (e.g., haptic feedback, visual feedback, audible feedback, etc.) to user P₁ based on the data received from sensor system 90 (e.g., external sensors 92, user sensors 94, etc.). For example, referring further to FIG. 8, user P₁ is shown to be within area 200, along with opponents O₁ and O₂. Opponents O₁ and O₂ are in close proximity (e.g., pose a possible threat, etc.) to user P₁, while opponent O₃ is not within a close proximity (e.g., does not pose a threat, substantially far from user P₁, not in play, etc.). As such, based on sensor data (e.g., head orientation, affiliation, position, movement, external data, user data, etc.) from sensor system 90, control system 20 is configured to provide feedback to user P₁ via feedback device 100. In one embodiment, feedback device 100 provides the user with feedback such that the user has a heightened awareness of the opponents and/or threats outside of his/her field of view. For example, opponent O₂ is not within the field of view of user P₁ such that user P₁ is unable to see opponent O₂. In other embodiments, feedback device 100 further provides the user with feedback for opponents within the user's field of view to reinforce the intuitive understanding of what each vibration or other type of feedback (e.g., audible, visual, etc.) represents or to establish an affiliation of the person in the user's field of view. For example, opponent O₁ is within the field of view of user P₁ such that user P₁ is able to see opponent O₁.

In one embodiment, feedback device 100 provides the user with feedback based on the gaze data such that the user has a heightened awareness of the opponents and/or threats that may be looking at them. The gaze data may provide an indication to the position and view angle of the opponents. The position of user and opponents may be defined by a global coordinate system such as a Cartesian coordinate system (X position, Y position, Z position, etc.) within area 200. The view angle of the opponents may be defined based on the orientation of a user's head. Thus, based on the position of the user, and the position and view angle of the opponent, control system 20 may determine whether the user is in or substantially near being within the opponent's line of sight. In some embodiments, feedback device 100 provides the user with feedback based on the gaze direction of opponents and/or a distance of the opponents relative to the user, as described above.

In some embodiments, sensor system 90 is configured to acquire environment data regarding potential hazards or dangers near the user. Feedback device 100 may provide feedback to the user based on the environment data and/or the user data. For example, a construction worker may be using feedback system 10 while working on a construction site. The feedback system 10 may monitor the surrounding area for potential hazards such as ledges, stairs, holes, trenches, hot surfaces or objects, hazardous materials or chemicals, sharp objects, moving equipment (e.g., vehicles, conveyor belts, rotating machinery, etc.), etc. Thus, if a user of feedback system 10 were to approach the hazard (e.g., unknowingly, etc.), feedback system 10 may be configured to warn the user not to move any closer, avoid contact, move in a proposed direction, etc. to prevent the user from encountering or engaging the hazard or danger (e.g., such that the user avoids the danger or hazard all together, to try to prevent harm from being inflicted onto the user, etc.). For example, a construction worker may be working on a skyscraper where there is a risk of falling over an edge of one of the floors. Feedback system 10 may be configured to warn the user when they approach the edge of the building such that they do not move any closer. In another example, sensor system 90 may include infrared cameras (e.g., in a manufacturing environment, in a labspace, etc.) that may facilitate feedback system 10 to warn a user not to touch an object or keep hands away because of a relatively hot surface. In yet another example, feedback system 10 may be configured to warn the user to move or not to move based on approaching objects or equipment (e.g., vehicles, fork lifts, cranes, tractors, skid-loaders, not in the sight of the user, etc.).

Feedback system 10 may also be able to monitor the condition of the user. Thus, sensor system 90 may acquire condition data indicative of a condition of the user. For example, feedback system 10 may be configured to monitor conditions of the user such as heart rate, breathing patterns, temperature, sleeplessness/alertness, SpO₂ levels, glucose levels, hydration levels, and/or other conditions that may be affected during sports, physical activity (e.g., running, etc.), and/or work (e.g., construction, surgery, etc.). Feedback system 10 may be configured to provide feedback to the user regarding his/her physical condition (e.g., changes thereof, condition readings exceeding or falling below a threshold value, etc.) such that the user may take appropriate action (e.g., take a break, get some sleep, eat some food, drink some fluids, etc.).

Communication Protocols

Referring now to FIGS. 10A-10C, user P₁, opponents O₁ and O₂, sensor system 90, and/or control system 20 may communicate with each other in a variety of ways, using any suitable wired and/or wireless communications protocols. User P₁ generally includes one or more user sensors 94 and one or more feedback devices 100 (see, e.g., FIG. 9). In one embodiment, control system 20 is implemented as a remote system configured to communicate with one or more users of feedback system 10 (e.g., via corresponding feedback devices 100, etc.). For example, referring to FIG. 10A, user P₁, opponent O₁, and opponent O₂ are configured to communicate user data, gaze data, and/or environment data to control system 20, which is in turn configured to receive external data, gaze data, and/or environment data from external sensors 92. Control system 20 is configured to provide feedback to each user based on at least one of user data, gaze data, environment data, and external data to increase the awareness of each user regarding threats around them (e.g., opponents, etc.).

In other embodiments, control system 20 is implemented into equipment worn, carried, or otherwise moving with the users of feedback system 10, such that the devices of user P₁ and opponents O₁ and O₂ can communicate directly with one another. For example, referring to FIG. 10B, user sensors 94 are configured to acquire user data, gaze data, and/or environment data regarding user P₁ and/or opponents O₁ and O₂. Based on the user data, gaze data, and/or environment data, control system 20 of the respective user (e.g., user P₁, opponent O₁, etc.) is configured to provide feedback to the user. In one embodiment, users with the same affiliation (e.g., same team, etc.) communicate with one another (e.g., regarding feedback received, etc.) such that a user may receive advanced notification of opponents/enemies near other users with the same affiliation. This example embodiment is able to be used in ad hoc environments (e.g., unfamiliar environments, hostile environments, environments without external sensors 92, etc.). For example, the configuration shown in FIG. 10B may be implemented with soldiers in hostile environments or for training purposes.

In further embodiments, user P₁, opponent O₁, and/or opponent O₂ are configured to communicate user data, gaze data, and/or environment data to at least one of control system 20 and other users/opponents, which are in turn configured to receive gaze data, environment data, and/or external data from external sensors 92. For example, referring to FIG. 10C, control system 20 is configured to provide feedback to each user based on at least one of the user data, the gaze data, the environment data, and the external data to increase the awareness of each user regarding threats around them (e.g., opponents, etc.). In one embodiment, users with the same affiliation (e.g., same team, etc.) communicate with one another (e.g., regarding feedback received, etc.) such that a user may receive advanced notification of opponents/enemies near other users with the same affiliation.

Feedback Actuation Functions

According to an exemplary embodiment, processing circuit 30 is configured to provide feedback to the user of feedback device 100 based on a feedback actuation function. The feedback actuation function may include a presence actuation function, a distance actuation function, and/or a direction actuation function. The presence actuation function is configured to provide a sense of a presence of an object (e.g. another person, a secondary object, within a proximity of the user or primary object, etc.). The sense of the presence may include a sense of a scale, an energy, a mass, a movement capability, a nature, and a threat level of the object, among other possibilities. The presence actuation function may provide a user or give the user the ability to provide a sense of a threat or friendliness. For example, a user may receive feedback from another person, such as a stroke along the back or a hugging sensation, to provide a sense of comfort. This may be implemented in situations such as a parent providing comfort to his/her premature baby that is isolated from physical contact or family members living apart from one another and being able to give a loved one a simulated hug, among other examples.

The distance actuation function is configured to provide a sense of a distance of an object relative to the user or primary object. The direction actuation function is configured to provide a sense of a direction of an object relative to the user or primary object. The relative priority of the presence actuation function, the distance actuation function, and the direction actuation function may vary responsive to the distance, the direction, and the nature of the object relative to the user or primary object. In some embodiments, the feedback actuation function is based on the relative position of elements 102 on the user of feedback device 100, the relative position of the user, and/or the relative position of the object. By way of example, feedback may need to be provided in a desired location, however the position of elements 102 may not facilitate the application of feedback in the desired location. Therefore, the feedback actuation function may actuate various elements 102 around the desired location. For example, processing circuit 30 may actuate elements 102 in a circular pattern around the desired location to indicate the location in which feedback is desired to be provided.

The feedback actuation function may be a continuous function, a discrete function, a linear function, a non-linear function, or any combination thereof. By way of example, the distance actuation function may increase an amplitude of the feedback linearly as an object (e.g., another person, a secondary object, etc.) gets closer to the user or primary object, or vice versa (e.g., inversely proportional to the distance, etc.). By way of another example, the distance actuation function may increase the amplitude of the feedback non-linearly (e.g., exponentially, quadratically, etc.) as an object (e.g., another person, a secondary object, etc.) gets closer to the user or primary object, or vice versa.

In one embodiment, processing circuit 30 is configured to modify the feedback actuation function responsive to a user response to previously-provided feedback (e.g., reduce, amplify, alter, etc.). The user response may include, but is not limited to, a body movement, a head movement, a temperature, a heart rate, a skin conductivity, a facial expression, a vocal expression, pupil dilation, brain waves, and/or a brain state. By way of example, processing circuit 30 may actuate various elements 102 as a user of feedback device 100 rotates his/her head. For example, processing circuit 30 may provide a vibration to a side of a user's head to indicate an object is to the user's side. As the user turns his/her head, the direction actuation function may modify which elements 102 provide feedback to the user such that the vibrations move as the user's head turns until the user's head is facing the indicated direction (e.g., the vibrations may move counter-clockwise as the user turn his/her head clockwise, etc.). The various functions disclosed herein may be embodied as instructions or programs implemented on or accessed by feedback system 10. In one embodiment, the instructions and/or programs are stored locally in memory (e.g., memory 38, etc.) of feedback system 10. In another embodiment, the instructions and/or programs are accessed via any suitable wired or wireless communication protocol to an external memory or via the Internet. Access to the Internet may provide for the ability to update the instructions and/or programs of feedback system 10 (e.g., periodically, when an update is released, etc.).
